C-Corp Tax Return Preparation for CPA Firms

Accountably is a staffing and recruiting agency that helps US CPA, EA, and accounting firms hire talent from India across tax, accounting, payroll, and finance. Accountably offers offshore staffing services, placing full-time offshore employees from India who work inside your firm's workflow, on your software and SOPs.

Accountably places corporate tax professionals in India across the whole 1120 cycle, from the trial balance and the book-to-tax reconciliation to fixed asset schedules, quarterly estimates, and the state returns that follow.

If a C-corp tax role can be performed remotely, Accountably can fill it with A-players from India.

Here are some examples of the roles we can fill:

• Corporate returns: business tax preparers, tax preparers
• Review: tax reviewers
• State corporate returns: SALT specialists
• The books behind the return: staff accountants

Accountably's staffing model is fully managed: we handle the employment contract, payroll, tax compliance, benefits administration, and salary disbursement for every hire, so you get the talent without the administrative overhead.

This matters most for firms that don't have an established entity or employer of record (EOR) infrastructure in India.

You direct the day-to-day work; Accountably handles everything on the back-end.

Our staffing model also includes onboarding support, equipment coordination if needed, and ongoing HR support for as long as the engagement runs.

Dedicated hires and build-operate-transfer teams go through the same vetting and shortlisting process; a white-label team is staffed and run by its assigned manager.

The core difference between dedicated offshore talent and a white-label delivery team is who directs the work. With dedicated offshore talent, your preparer works inside your workflow and you direct the work like any member of your team; with a white-label delivery team, Accountably's manager runs the team, with its own reviewers, and you review the finished returns.

Recruiting differs between the models. Dedicated hires go through the same recruiting process as build-operate-transfer teams, while a white-label team is staffed and run by its assigned manager.

Dedicated offshore talent is the right fit if you have round-the-year corporate tax work, quarterly estimates included, and want full-time staff inside your workflow.

A white-label delivery team makes more sense if your C-corp volume spikes ahead of the April deadline and you'd rather review finished returns. Firms serious about long-term offshore control can also choose build-operate-transfer.

If you're not sure which fits your situation, mention it on the discovery call, and the team will walk you through all three options.

Accountably quotes every C-corp tax seat before you commit. Tax seats start from about $14 an hour, which comes to roughly $2,400 to $2,500 a month for a full-time seat. Senior seats, such as a tax reviewer who runs the senior and quality review, are quoted on request.

For a dedicated hire, Accountably prices the seat, not the return, so a fixed asset history that needs rebuilding is capacity you already have rather than a change order. White-label work is billed per return for tax work; other work is priced by scope, agreed on your discovery call.

The rate can vary by role and seniority, so you will get the specific figures on your discovery call, where we will walk you through the total cost for the role you need to fill.

But even with Accountably's fee included, a C-corp tax hire in India through Accountably can still save your firm up to 46% compared to an equivalent US hire.

For firms that don't have an existing international payroll setup or in-country legal infrastructure, the staffing model removes that work entirely. Accountably handles the employment contract, payroll processing, tax compliance, and benefits administration for your hires.

You direct the work. Accountably owns the employment relationship.

Also, with Accountably you pay nothing until you hire. The search, sourcing, shortlisting, and your interview stages all happen before any fee is due. If Accountably does not place someone, you owe nothing. A dedicated hire has a 60-day minimum commitment.

The 45-day replacement guarantee is included. If a placement does not work out within 45 days, Accountably finds a replacement at no additional charge.

Outsourced corporate tax preparation is the practice of handing your C-corp clients' Form 1120 work to a team outside your firm instead of hiring more in-house preparers. That team prepares the return from the trial balance, reconciles book income to taxable income on Schedule M-1 or M-3, calculates the quarterly estimates, and handles multi-entity consolidation, all inside your tax software and ready for your review.

A C-corp pays federal income tax at a flat 21% rate at the entity level, and its shareholders are taxed again when after-tax profit is paid out as dividends.

For a CPA or accounting firm, the work usually covers:

• Form 1120 with its schedules: C (dividends), J (tax computation), K, L (balance sheet), M-1, and M-2
• Schedule M-3 in place of M-1 for corporations with $10 million or more in total assets
• Temporary and permanent book-to-tax differences, carried forward year over year
• Quarterly estimated tax calculations with the safe harbor and annualized income methods
• Consolidated returns for parent-subsidiary groups, with intercompany eliminations and E&P tracking
• Fixed asset and depreciation schedules
• Current and deferred tax provision calculations, with ASC 740 support documentation
• State corporate returns with apportionment and state addback and subtraction modifications

Outsourced means the work is done by a team outside your firm. Offshore means that team is in another country. With Accountably it is both: your preparer sits in India and works inside your workflow like any other member of your team.

The main difference is cost. A C-corp tax hire in India can save your firm up to 46% compared to a US-based equivalent, due to the lower cost of living in India compared to the US.

With dedicated offshore talent, your firm manages the day-to-day work. Your preparer reports to your managers, follows your workflows and processes, and works as part of your team, just like any other remote employee.

Accountably doesn't direct their daily work or assign client returns. You have complete control over their responsibilities and schedules. Think of Accountably as the hiring and administrative partner, not a management layer.

If you'd rather review finished returns than direct the work, a white-label delivery team comes with Accountably's own manager and reviewers.

Yes, tax preparers in India working with US firms work in the same tools your team already relies on: UltraTax CS, CCH Axcess, Lacerte, Drake Tax, and ProConnect Tax for the returns, QuickBooks and Xero for the client books behind the trial balance, and Karbon, TaxDome, and Suralink for workflow and client documents.

During vetting, Accountably screens explicitly for your stack rather than assuming tool familiarity and runs the assessments you already use.

Onboarding then ramps your preparer on your firm's software and SOPs, from your workpaper standards to your M-1/M-3 procedures and consolidation workflows. There is no migration and no change to how your firm reviews or files returns.

If there is a specialized system in your clients' environment, we identify transferable skill paths and flag any ramp time upfront so you can make an informed decision.

Accountably puts every candidate through a rigorous screening process before presentation.

Every candidate goes through Accountably's vetting process, which includes:

• Skills assessment: technical evaluation specific to the role requirements
• Experience validation: Accountably verifies work history
• Software experience: we check every candidate's experience in the tax software your firm files from, such as UltraTax CS, CCH Axcess, Lacerte, Drake Tax, or ProConnect Tax
• Cultural fit: Accountably screens for alignment with US business practices, work style, and your specific firm culture
• Motivation check: Accountably rules out candidates who are just looking for short-term contracts or salary bumps
• Background checks: we run background checks, and every hire works under an NDA

You only see candidates who meet all these criteria. Experienced hires start with onboarding on your software and SOPs. Newer hires first complete our 6-week US tax and accounting program.

Form 1120 is generally due by the 15th day of the fourth month after the corporation's tax year ends. For a calendar-year corporation that is April 15, moved to the next business day when it falls on a weekend or legal holiday.

Form 7004 gives an automatic extension of time to file, generally 6 months, but it does not extend the time to pay, so any balance is still due by the original date.

A corporation that expects to owe $500 or more for the year pays its tax in four quarterly estimated installments, and missing or underpaying an installment triggers a penalty.

Your team calculates the estimates with the safe harbor, annualized income, and adjusted seasonal installment methods, with payment vouchers and a variance analysis. It prepares the Form 7004 alongside the 1120 work and flags the estimated balance due, so your firm's payment lands on time.

Yes, on a senior seat. The team prepares consolidated returns for parent-subsidiary groups, including intercompany eliminations, basis adjustments, excess loss account tracking, and E&P computation, and complex multi-entity groups go to senior preparers.

State corporate income tax returns are prepared with the apportionment calculations, nexus analysis support, and state-specific addback and subtraction modifications, and coordinated with the federal 1120 so the numbers agree.

Where nexus itself is the question rather than the filing, the determination stays with your firm. See SALT specialists for the state seat.

Every return gets a dedicated book-to-tax reconciliation review, where each difference between book income and taxable income is mapped to the proper temporary or permanent category and carried forward to next year's schedule.

Returns that file Schedule M-3 go through an additional validation step, so that Part II and Part III tie properly.

For the tax provision, your team prepares the current and deferred tax calculations, the effective tax rate analysis, and the ASC 740 support documentation. The deferred tax judgment, any valuation allowance, and the final provision sign-off stay with your firm.

Every file goes through preparer, senior, quality and final review before it reaches you:

• A trained corporate tax preparer builds the 1120, the schedules, and the structured workpapers on your SOPs.
• A senior reviewer checks the book-to-tax reconciliation, the M-1/M-3 classification, the estimated tax, and the consolidation entries.
• A quality reviewer ties Schedule L, Schedule M-2, and the provision schedules, and confirms the state apportionment holds.
• A final review packages the return and workpapers in your format, ready for your partner's sign-off.

Your firm keeps the signature, the e-file under its own EFIN, the final judgment on positions and elections, and the partner-level call on book-tax differences and consolidation treatment.
